The dose of the compound of the present invention to be used as a herbicide varies depending on application place, application time, application method, target weeds, crops to be grown, etc., but its dose as an active ingredient is generally suitably 0.001 to 50 kg, preferably 0.01 to 10 kg per hectare (ha).

Further, the compound of the present invention may be mixed with other kind of herbicide, various insecticides, fungicides, plant growth regulators and synergists, etc. at the time of formulation or application, if necessary.

Particularly when the compound of the present invention is mixed with other kind of herbicides, there can be expected lowering of cost because the dose of the compound of the present invention to be used is decreased, a herbicidal spectrum enlarged by synergism of the mixed chemicals and a higher herbicidal effect. Also, the compound of the present invention can be mixed with plural known herbicides simultaneously.

As a kind of the herbicide to be mixed with the compound of the present invention, there may be mentioned, for example, compounds described in Farm Chemicals Handbook published in 1993, etc.

As a preferred chemical to be used by mixing with the compound of the present invention, there may be mentioned, for example, pyrazosulfuron ethyl (common name), bensulfuron methyl (common name), cinosulfuron (common name), imazosulfuron (common name) and DPX-A8947 (N-(((4,6-dimethoxypyrimidin-2-yl)amino-carbonyl))-1-methyl-4-(2-methyl-2H-tetrazol-5-yl)-1H-pyrazole-5-sulfonamide).

Also, in addition to these chemicals, the following components may be further added.

There may be mentioned pretilachlor (common name), esprocarb (common name), pyrazolate (common name), pyrazoxyfen (common name), benzofenap (common name), dymron (common name), bromobutide (common name), naproanilide (common name), clomeprop (common name), CNP (common name), chlomethoxynil (common name), bifenox (common name), oxadiazon (common name), mefenacet (common name), butachlor (common name), butenachlor (common name), dithiopyr (common name), benfuresate (common name), pyributicarb (common name), benthiocarb (common name), dimepiperate (common name), molinate (common name), butamifos (common name), quinclorac (common name), cirmethylin (common name), simetryn (common name), SAP (bensulide/common name), dimethametryn (common name), MCPA, MCPB, 2',3'-dichloro-4-ethoxymethoxybenzanilide (test name is HW-52), 1-(2-chlorobenzyl)-3-(α,α-dimethylbenzyl)urea (test name is JC-1940), N- 2'-(3'-methoxy)-thienylmethyl!-N-chloroacetyl-2,6-dimethylanilide (test name is NSK-850), etc.

When the compound of the present invention is used as a herbicide, it can be generally used by mixing with a suitable carrier, for example, a solid carrier such as clay, talc, bentonite, diatomaceous earth, white carbon, etc. or a liquid carrier such as water, alcohols (isopropanol, butanol, benzyl alcohol, furfuryl alcohol, etc.), aromatic hydrocarbons (toluene, xylene, etc.), ethers (anisole, etc.), ketones (cyclohexanone, isophorone, etc.), esters (butyl acetate, etc.), acid amides (N-methylpyrrolidone, etc.) or halogenated hydrocarbons (chlorobenzene, etc.) and others. If desired, by adding a surfactant, an emulsifying agent, a dispersant, a penetrant, a spreading agent, a thickener, an antifreezing agent, an anticoagulant, a stabilizer, etc., the compound of the present invention can be provided for practical use in any desired preparation form such as a liquid formulation, an emulsifiable concentrate, a wettable powder, a dry flowable powder, a flowable liquid, a dust, a granule, etc.

To describe a herbicidal granule for a paddy field, containing the compound of the present invention specifically, as a solid carrier, there may be mentioned kaolinite, montmorillonite, diatomaceous earth, bentonite, talc, clay, calcium carbonate, calcium sulfate, ammonium sulfate, etc., and as a surfactant, there may be mentioned alkylbenzenesulfonate, polyoxyethylene alkylaryl ether, lignosulfonate, alkylsulfosuccinate, polyoxyethylene aliphatic acid ester, naphthalenesulfonate, polyoxyethylene alkylaryl ether sulfate, alkylamine salt, tripolyphosphate, etc. The content of these surfactants is not particularly limited, but it is generally desirably in the range of 0.05 to 20 parts by weight based on 100 parts by weight of the granule of the present invention. Also, if necessary, a decomposition inhibitor such as epoxidized soybean oil, etc. may be contained in the granule of the present invention.

Next, formulation examples of preparations when the compound of the present invention is used are shown specifically. However, formulation examples of the present invention are not limited to these. In the following Formulation examples, "part" means part by weight.

The above components are mixed uniformly and pulverized, and then a small amount of water is added thereto. The mixture is stirred, mixed and kneaded, and granulated by an extrusion type granulator, followed by drying, to prepare a granule.

When the above wettable powder, emulsifiable concentrate, flowable liquid or granular wettable powder is used, it is diluted to 50 to 1000-fold with water and sprayed so that its active ingredient is 0.001 to 50 kg, preferably 0.01 to 10 kg per hectare (ha).

The compound of the present invention can be used as a herbicide for a paddy field in either treatment of soil treatment under submerging condition or stem and foliar treatment. Also, the compound of the present invention can be used as a herbicide for an upland field in either treatment of soil treatment, soil incorporation treatment or stem and foliar treatment, and can be also applied suitably to control of various kinds of weeds in noncultivated fields such as a playground, a vacant land, a space beside a railroad track, etc. other than the agricultural and horticultural field such as a paddy field, an upland field, an orchard, etc.

Next, usefulness of the compound of the present invention as a herbicide is described specifically by referring to the following Test examples.

Test Example 1 Test of Herbicidal Effects by Soil Treatment

Plastic boxes each having a length of 21 cm, a width of 13 cm and a depth of 7 cm were packed with sterilized diluvial soil, planted with seeds of barnyardgrass (A), green foxtail (B), velvetleaf (C), redroot pigweed (D), morning glory (E), soybean (a), cotton (b) and corn (c) in a spotted state, respectively, and covered with about 1.5 cm of soil. Then, chemical solutions were uniformly sprayed on the soil surfaces by small sprays so that the amounts of the active ingredients of the compounds of the present invention became specific ratios. The chemical solutions for spraying were used by diluting wettable powders suitably prepared according to Formulation examples described above, etc. with water. Three weeks after spraying the chemical solutions, herbicidal effects on the crops and the weeds were examined according to a judgment standard described below. The degree of control was determined by observation with naked eyes.

5: Completely killed or 90% or more of control

4: 70% to 90% of control

3: 40% to 70% of control

2: 20% to 40% of control

1: 5% to 20% of control

0: less than 5% of control

Test Example 3 Test of Herbicidal Effects Under Submerging Condition

Wagner pots each having an area of 1/10000 are were packed with alluvial soil, and water was poured into the pots mixed with the soil to make a submerging condition of a water depth being 4 cm. After seeds of barnyardgrass (A), bulrush (G), ducksalad (H) and toothcup (I) were sowed in the above pots, seedlings of rice (d) at 2.5 leaf stage were transplanted. One day after sowing, chemical solutions were subjected to dropwise treatment to the water surfaces by measuring pipettes so that the amounts of the active ingredients of the compounds of the present invention became specific ratios. The chemical solutions for dropwise addition were used by diluting wettable powders suitably prepared according to Formulation examples described above, etc. with water. The pots were placed in a greenhouse at 25° to 30° C., and the plants were grown. Three weeks after dropwise addition of the chemical solutions, herbicidal effects on rice and the weeds were examined according to the judgment standard of Test example 1. The results are shown in Table 9.
